| CdS Microspheres: Hydrothermal Synthesis and UV-Vis Spectroscopy |

| 摘要: 本文以水热法制得了CdS微球体，采用XRD、SEM、TEM等测试手段对产物进行了表征。实验结果表明，硫源、溶剂及其浓度对产物的形貌有显著影响。在180 ℃下，以硫脲为硫源，EDTA-二钠饱和水溶液为溶剂制得的CdS微球体具有良好的形貌，外形规则，直径大约2~5 μm。紫外-可见光谱分析表明CdS微球体的吸收峰与体相CdS相比出现了蓝移。 |

| Abstract: CdS microspheres were prepared by hydrothermal method. XRD, SEM and TEM techniques were used to characterize the as-synthesized CdS. It was found that the size and morphology of the as-synthesized samples were affected strongly by the sulfur sources, solvents as well as their concentrations. As a result , the CdS microphreres with narrow size distribution and uniform morphology are approximately 2~5 μm in diameter. The result of UV-Vis spectroscopy measurements reveals that the absorption peak of CdS microspheres is blue-shifted compared with that of bulk CdS. |
